I use KDE Neon on my laptop and I’d prefer to have KDE as a DE on this one too (if possible) but I don’t mind a non Ubuntu base. Basically I’d just like to be able to play games on it without much hassle but I know how to paste commands into the terminal if the need arises.
I faintly remember having to deal with that. There’s a built-in “Device Auto-Mount” app that may be able to help with that without messing with fstab, assuming the drives are recognized.
